Please review JDK-8059811, "turn off optimistic types for 8u40 by default."

This is the CR: https://bugs.openjdk.java.net/browse/JDK-8059811
This is the webrev: http://cr.openjdk.java.net/~lagergren/8059811.3/
This is the thread: http://mail.openjdk.java.net/pipermail/nashorn-dev/2014-October/003617.html

When it goes back to 8u40, I will change the default from ‘true’ to ‘false’ in Options.properties and from ‘true’ to ‘false’ in TestFinder.java. Both configurations have been tested.
